Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants

Devices and methods that allow a rod to be offset in a relatively small amount of space are disclosed herein. In some embodiments, first and second offset rods can be joined by a plate-type connector having a reduced thickness suitable for insertion into a small space, e.g., between adjacent bone anchors. In some embodiments, first and second offset rods can be joined by a curved connector that conforms to adjacent bone anchors and likewise has a reduced thickness.
